I have a Plextor 24x10x40 and a Liteon 40x12x48. I am an=ble to write to both drives at the same time with Nero 126.96.36.199. The problem is it hangs at 100%. I have to restart the computer in order to quit the program. When I try the cd's afterwards, they do work. I'm not sure why it hangs. If anyone has any ideas, please let me know.
